What are fossils reading comprehension?
Fossils are shapes of dead animals and plants that lived millions of years ago made in rock. Usually when something dies it is eaten or decays and disappears. However, when an animal or plant dies and gets covered over, it can stay there and over time, become a fossil.
What are fossils Readworks?
Fossils are the remains of ancient life that are usually buried in rock. Most fossils formed from the hard parts of organisms such as teeth, shells, and bones. They also form from things a plant or animal leaves behind, like a footprint, a leaf print, and even eggs. Fossils show us what Earth was like long ago.
How are fossils formed in reading?
As a bone slowly decays, water filled with minerals seeps into the bone and replaces the chemicals in the bone with other minerals that are as hard as a rock. Most fossils are dug up from sedimentary rock layers. Sedimentary rock is rock that has formed from sediment, like sand, mud, and small pieces of rocks.

What can you learn from dinosaur fossils?
By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils can tell us a lot about the past.

Why is it important to understand dinosaurs?
The study of dinosaurs is crucial to understanding to the mechanics of evolution. Scientists around the world today are undertaking extensive research on extinction, using dinosaur fossils to understand the biodiversity of the Earth millions of years ago.
What are the 5 types of trace fossils?
Tracks, burrows, eggshells, nests, tooth marks, gastroliths (gizzard stones), and coprolites (fossil feces) are examples of trace fossils or ichnofossils. Trace fossils represent activities that occurred while the animal was alive. Thus, trace fossils can provide clues to diet and behavior.
